Hello, I'm Pachu Kannan. I noticed that you recently removed content from Dennis Ritchie without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.

Please do not add or change content, as you did at Edwin McMillan, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article.   Pachu Kannan (talk) 10:20, 6 September 2021 (UTC)
